The gauche effect is explained by hyperconjugation and electrostatic interactions
The gauche effect in fluorinated compounds is predominantly explained by a combination of hyperconjugative electron delocalization and electrostatic interactions.
The retrieved papers consistently support the claim that the gauche effect (particularly in organofluorine systems) is governed by stereoelectronic forces, specifically hyperconjugation and electrostatic interactions.

Paper 3 notes that the C-F bond aligns predictably due to stereoelectronic effects including hyperconjugation and electrostatic attraction.
